Premium Synthetic Racing Motor Oil - 1 Quart (32 Ounces)

Motor oil, derived from crude oil, serves to lubricate, clean, and cool engines. Unlike traditional oils, fully synthetic variants like Royal Purple's are not crude-based, offering superior performance. This includes enhanced gas mileage and reduced wear under extreme temperatures. Motor oils vary in viscosity and additives, with a Society of Automotive Engineers (SAE) numerical code indicating thickness—higher numbers mean thicker oils. For example, SAE 20W-50 denotes viscosity ratings of 20 in cold and 50 at normal temperatures.

Racing oils, designed for high-compression and motorsports vehicles, prioritize horsepower and friction reduction with specialized additives. Royal Purple's Extreme Performance Racing Oil, such as the XPR line, dominates various motorsports due to its Synerlec technology. This technology bonds with metal parts, ensuring continuous protection and enhancing performance and longevity. The oil's high film strength minimizes friction and heat, maximizing power transfer and extending service life. Over time, it smooths metal surfaces, potentially creating a mirror-like finish.

XPR oils come in different viscosities tailored for specific racing needs. Ultra-light variants like XPR 3.1 and XPR 0W-10 suit competition engines, while others like XPR 5W-20 and XPR 20W-50 are suitable for street and track vehicles. However, they do not conform to API or ILSAC standards and may not comply with some warranties.

Royal Purple offers various options for racers, with HPS oils outperforming many rivals, while XPR redefines racing oil standards with even higher performance. Choosing between HPS and XPR depends on the engine's build tolerance and specific requirements. For instance, engines with looser tolerances may benefit from heavier oils to maintain optimal pressure.

Royal Purple's lubricants are compatible with exotic fuels, formulated to combat emulsification in alcohol and methanol applications. They can be used on newly coated bearings without requiring a mineral oil break-in period. Moreover, they contribute to lower oil temperatures by 5-20°F in vehicles with well-maintained cooling systems.

In summary, Royal Purple's synthetic oils, particularly the XPR line, offer exceptional performance benefits in motorsports and high-performance applications. Their advanced additive technology, Synerlec, ensures superior protection, efficiency, and longevity compared to conventional oils. Whether on the track or the street, Royal Purple remains a top choice for professionals and enthusiasts seeking peak engine performance and durability.
